DNSChanger has been there since 2007, but it is to affect the infected PCs the worst on Monday, July 9, 2012. In order to decrease the impact of the virus, FBI has taken several precautions. As part of it, the American intelligence agency will shut down servers of PCs affected with the malware. That is, users from those systems won’t be able to access the web on that day.
FBI and various computer security firms including MacAfee are working hard to clean the virus. However, some infected computers may not be able to connect to internet further.
